Bien sur
Funny I was looking up getting a new lid and only read today that in France you're technically supposed to have extra hi viz stickers on the back and sides (I think). Stolzy will know but I can't recall him or me ever having them adhered in the past. His advice on the Priority a droite rule is however crucial. Read it up otherwise you could be in for a shock ... or worse. One of the best countries in the world to ride in IMO.
The sticker law has been a requirement in France for years, I bought a helmet for the wife recently, and got a pack of stickers in it, which are reflective. To be applied front, rear, and each side. I've never heard of anyone being pulled up on it however, and reckon if you're a Brit, driving sensibly, you'd be unlikely to fall foul of the law.
The priority a droite rule is DEFINITELY something you want to be aware of though. It's normally applicable only in built up areas.
In this image, the sign with the cross on it, means priorite a droite, so that car will likely pull right out without even looking and if you tbone him, it's YOUR fault.
Apart from that sign, there are also these two,
This one means, you're on a road which no longer has priority, and you often see that when coming into villages or built up areas.
This one, is known as 'priorite ponctuelle' and means YOU have priority, but only over the junction immediately after the sign, so once past the junction, if it's built up, assume priorite a droite.
It sounds scary and complicated but it was designed to slow people down in built up areas and it works in that respect. Once you are in the open, generally, whichever road you're on in the countryside, you will have priority.
In built up areas, ride through villages as if a tractor could appear out of nowhere and pull right out in front of you at the last minute. Seriously the police are really cracking down on people speeding through villages and towns, and if you have UK plates, you WILL have the book thrown at you. If you ride at 30kph instead of 100 through most villages, ye never know, you might find a gem of a cafe.
Enjoy, oh, and ride on the right
